What makes compound microscopes so special?

Modern day compound microscope can magnify an object to a thousand times its original size. It can distinguish objects placed as closely as 0.1 micrometers. Multiple convex lenses lined at accurate distances are placed in this microscope to achieve greatest magnification, which is not producible by a single lens.

One of the lenses is placed at the eyepiece to generate magnification. Through this lens, users can observe the slides placed under the microscope. This lens can magnify an object ten times the normal size.

Objective lens combines multiple lenses (typically three to four), at the rotatable nosepiece. Users can change the degree of magnification by selecting the right lens, by rotating the nosepiece.

A typical compound microscope consists of four lenses: a low power lens that can magnify an object up to ten times, high-power one that can magnify it up to 40 times, oil immersion lens that can enlarge the image hundred times, and the scanning glass that can make the sample appear four times bigger.

This laboratory tool is used in almost every scientific field. Biology students use it in colleges for study. Biology is the field that has found its usage at the largest scale. It is routinely used by people in hospitals for research and diagnosis related work by analyzing the samples obtained from patients.
